Pepper quota support
Probably this could be better implemented using push notification model, but in this patch I made this very straightforwardly (with possibly minimal change). **NOTE: This design may not be really safe as quota accounting is done in renderer**
* Added QuotaFileIO class (in quota_file_io.{cc,h}) which performs pre- and post- write quota related operations.
* For Write/SetLength the QuotaFileIO instance first performs QueryFileInfo and QueryAvailableSpace to get the file size and current available space. If the results look good it dispatches actual Write/SetLength operations. After the operation has succeeded it then notifies the browser that it has made a storage modify operation.
* For WillWrite/WillSetLength this change assumes they are always followed by actual write/setlength operations and the operations will succeed.
Based on another cleanup patch:
